Abstract

A flow sensor is provided responsive to fluid leakage flows within a range from above a predetermined minimum to below a predetermined maximum, to indicate that leakage flow is within that range and/or that maximum leakage flow has been exceeded, but nonresponsive to fluid flows below the predetermined minimum or above the predetermined maximum, to avoid giving a false indication of fluid leakage flow, comprising a flow responsive valve and a differential pressure indicator sensing differential pressure between fluid leakage flow and normal fluid flow at the valve.
